I MEDICAL APPLIANCE Filed March 121 1951 INVENTOR, Irvz'ngFreed. ATTORNEPatented Dec. 23, 1952 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to medical appliances, and especially to thecombination of a specific medical composition and its container,comprising a dual-service lotion in a bottle or the like, whichcontainer includes a concavity or trap and is operable to effectselective applications of said composition onto and for treatment ofscalps that have diiferent degrees of oiliness; said container beingunpartitioned, or having a single cavity, which has a neck oroutlet-element, and has an oil-trap or concavity at the base of saidneck. The container is preferably transparent, so the condition of themedical composition therein can be seen by the user for determining whenit is ready for use on oily scalps, or for use on dry or non-oilyscalps.

The dual-service lotion consists of menthol, phenol andresorcinol-mono-acetate, as the prin cipal medicinal ingredients, plusethyl alcohol and pure water as the medicinal vehicle, plus castor-oilor other oil which is both cohesive and adhesive and is insoluble inwater and in a solution of more Water than alcohol and which has agreater specific gravity than that of such solution.

One practical formula of said dual-service tion is as follows:

Per cent Distilled or filtered water, by volume 50 180 proof ethylalcohol, by volume 45% Menthol, by volume "l Phenol, by volumeResorcinol-mono-acetate, by volume 2 Castor oil, by vo1ume 2 However:other formulas are productive of effective results, for instance wherethe percentage of alcohol may be as low as 38% or a little lower, andthe water about 57% or a little higher, the castor oil remains in aglobule at the bottom of the container; but will rise to the surface ofthe solution if the percentages of alcohol and water are respectivelydecreased and increased to a few degrees beyond the figures given above.However: The percentage of alcohol may be raised as high as 70%, and thepercentage of water as low as without the specific gravity of thevehicle exceeding that of the castor oil and causing it to rise to thetop or surface of the vehicle; the sum of said medicinal ingredientsbeing 5%.

It may be seen, therefore, that the gist of this invention is inproperly proportioning the water and alcohol for keeping the specificgravity of the solution less than that of the oil therein, so the oilsinks and forms a distinct globule that remains at the lowest part ofthe bottle or container and does not intermix with the other ingredientsexcept when the solution is agitated, as by the user briskly shaking thecontainer so as to break up the globule into tiny particles that areheld in suspension temporarily while a portion of the lotion is beingapplied on a relatively dry scalp that needs oil along with the otheringredients.

However: when the container is left undisturbed for a while, the tinyparticles soon settle to the lowest part of the container and coalesceinto a distinct globule, or into separate globules that gravitate towhatever may be the lowest part of the container, whether the containeris standing upright or is tilted to a nearly inverted position. When thelotion is poured while the globule or globules remain out of suspension,the oil is trapped in the concavity that adjoins the neck of the bottleor container, while the oilless liquid combination flows thereover andout from the neck and mouth of the container, as when the scalp is oilyenough without any added oil.

In the accompanying drawings, the invention is illustrated by Fig. 1which shows a transparent container tilted about from its normal uprightor vertical position, a part being broken away. Fig. 2 shows the samecontainer tilted to about from its normal upright position, a part beingbroken away.

Referring to these drawings in detail, wherein, similar referencenumerals refer to similar parts in both views, details of the inventionare described as follows:

The container is here illustrated as a transparent bottle thru which canbe seen the globule of oil 3 in the lowest part of the tilted bottle inFig. 1, and trapped in the concavity 4 in Fig. 2, adjoining the neck 5through which the oil-free liquid 6 flows, as seen in Fig. 2, when thebottle is tilted, and thru which the oil-permeated liquid flows if thebottle is sufficiently tilted immediately after it has been brisklyshaken.

There is nothing novel about the bottle, per se, and its onlyrequirement as to shape is that it must have an internal depression orconcavity or oil-trap therein; but it is also important that it betransparent and that the oil-free liquid be transparent, so the user cansee and discern when the globule has been sufficiently broken up as tobe held in suspension in the combination of other liquids, and to seethat the globule is and remains safely trapped when the bottle is tiltedin any direction, when it is desired to pour only the oil-free liquid ormixture from the cylindrical bottle whose trap 4 is circumferentiallycontinuous.

This invention is claimed as follows:

In a medical appliance, the combination of a container having a bottomand an outlet and having an oil-trap therein between said bottom andoutlet, a normally oil-free mixture of principal ingredients of adual-service lotion in said container, and a normally distinct globuleof coalescent oil in said container and having a greater specificgravity than that of said mixture and being gravity-operable to becomedetained in said oil-trap while a portion of oil-free mixture is beingpoured out through said outlet, said globule of oil being adapted tobecome diffused and suspended in said mixture by agitation of saidmixture and oil so that a portion of the said mixture and oil can thenbe poured out through said out let simultaneously.
